As you may know, Google has recently announced that sites with encrypted traffic (i.e. HTTPS) will have advantage over the rest of websites. This change will be applied gradually and Google will be giving somne guidelines to make the switch easier for the site owners, Apparently, this is a move to encourage webmasters to opt for HTTPS as standard.

My question is, are you already using HTTPS with your blog? Or do you plan to buy a SSL certificate soon? If yes, from where do you plan to buy one?
